Finding a div that contains some text

Copy linkTweet thisAlerts:
Jun 25.2014

Hello colleagues

I have a web page with a lot of divs in it. Some of them contain names such as Smith, Ms Ruth.
I would like the page to load then perform the following code to find the Id of the div in which Ms Smith might be in.
The following code works well in a much smaller page with only 3 divs in it but does not seem to work with the large html page.
I have consulted google till my hair falls out.
Any ideas ?

<script id=”myScript”>
var surname = “”;
surname = prompt(‘What is name?’);
alert(surname);//works fine up to here

function getID()
{
$(document).ready(function(){
var z = $(“div:contains(surname)”);
alert(z[0].length);
});//doesn’t work ? But did on a smaller page
}
getID();

</script>

@TcobbJun 25.2014 — This isn't tested. It also uses the "textContent" property which means it won't work with earlier versions of IE. It assumes that all your DIV's have an ID. If you send the word you're looking for as the arg it will return an array which will contain the ids of all DIV's in which that text occurs.

[CODE]function doFind(sought){
var i, len, arr, ids, div;
sought = sought.toLowerCase();
ids = [];
arr = document.getElementsByTagName('div');

len = arr.length;
for(i = 0; i < len; i++){
div = arr[i];
if(div.textContent.toLowerCase().indexOf(sought) >= 0){
ids.push(div.id);
}
}
return ids;
}[/CODE]

Success!
